iSpring Greatwell NSF Certified Reverse Osmosis Membrane 75 GPD 11.75” X 1.75”, Replacement Fits Standard Under Sink RO Drinking Water Filtration System, MC7

I got tired of paying $200 every year for my RO dealer to change filters and every time I asked for what filters they use, they would give me the run around and avoid straight answers, so did my own research and this filter kit is great has everything you need, easy to install and fits perfect, no leakage, water quality and clarity is really good, water taste is good, only issue I had was the activated carbon filter had the push connections and my old one had screw on type connections so I had to buy new connections, but now that it's done it will be easy to replace, Highly Recommend This RO Filter Kit.

I’ve been using iSpring reverse osmosis systems for years, and this 2-year replacement filter set is a total game-changer. The F19K75 set has everything I need to keep my 6-stage RO system running like new, and the fact that it’s NSF certified gives me extra peace of mind about water safety. Installation was straightforward—even for someone like me who's not exactly a plumber. All the filters are clearly labeled and well-packaged. I especially love the alkaline mineral filter—it really improves the taste of the water and helps balance the pH. It’s crisp, clean, and noticeably better than bottled water. The 19-count set is a great value and lasts the full 2 years as advertised, so I’m not constantly reordering or worrying about when to change them. It’s a small investment for long-lasting, high-quality water right from my tap. Highly recommended for anyone with an iSpring system. You can really taste the difference!

I’ve been using iSpring filters for a few years now, and this F19K75 2-Year Replacement Pack is by far one of the most convenient and reliable options out there. The installation was straightforward — everything fit perfectly into my iSpring RO system without any leaks or hassle. If you’re maintaining a 5-stage or 6-stage iSpring system, this pack is a no-brainer. Great value, easy installation, and excellent water quality. Highly recommend!

Ispring RO systems are truly amazing water quality. If you live in the city, this is a must have. Installation is quick and easy, took me about 15 minutes. I change these filters about once a year. The taste is clean and brings LA water down from 400 ppm to 20 ppm.

Used these before, the video created by Ispring is awesome, haven't had any issues yet!! Great price and does the job.

There is few years I use this product I like it but recent order had missing connection part in package so I can’t use my system.

Reverse osmosis water is the only way! My husband and I are water snobs now and take our own water with us everywhere. We've been regularly changing our filters since installing our system over 4 years ago. My recent replacement pack had a minor issue which iSpring quickly resolved. Thanks Sean! Great products and great customer service.

Great filters, great company. I recently needed a faucet replacement when my old one started to leak, and Nick was very accommodating.

I bought this product based on reviews. Everything is working excellent and everything as advertised. Another important part while purchasing a product is customer service, they are top notch. I had a few questions and Nick was there to walk me through every step.

2018年から使い出したRCC7P用にストックします。 ミネラルカートリッジも付いているので、配管含めて追加してみます。 入口が80～120ppmの水なのでフィルターの持ちが良い気がして、１～２年の交換周期を伸ばして使っています。基本的に浄水水量が確保されていれば、頻繁に交換する必要はないと考えている。

Muy buena membrana, me dura perfectamente 2 años sin problemas.

セットが便利。フィルターも信頼高い。

أجود وأضمن من الصيني اللي في السوق ، كنت أطلبه من أمريكا والان متوفر هنا ، نصيحة لا تبخل على نفسك وابحث عن الجودة هذا ماء تشربه 👍😎
